USB 2.0 Cable
Your Professional USB 2.0 Cable Supplier
USB 2.0 cable is standard cable based on second-generation Universal Serial Bus interface, mainly used to connect computers to various peripheral devices. Such as keyboards, mice, printers, external hard disk drives, etc. Standard USB2.0 cable features a USB2.0 interface connector on each side, linked with one pairs wire and two single wire, data transfer can speed up to 480 Mbps (High-Speed USB) while supplying power to connected devices.
Compared with original USB 1.1 standard, USB 2.0 has achieved comprehensive technical upgrades. It adopts a 4-wire differential signal transmission architecture to eliminate the traditional low-speed transmission mode, with a theoretical peak data transfer rate of 480 Mbps, which is 40 times that of USB 1.1 (12 Mbps). Meanwhile, it is fully compatible with old USB 1.1 and USB 1.0 devices, featuring outstanding universality as a standardized and generalized basic electronic accessory.
Features of USB2.0 Cable
USB2.0 data Cable uses differential signal transmission technology, which distinguishes the bidirectional data transmission logic of upstream and downstream. Supports three transmission modes: High-Speed, Full-Speed and Low-Speed to meet the demands of various devices. High speed USB2.0 cable supports to stably transmit documents, images and standard video files, eliminating lag and packet loss issues found in older interfaces, and satisfying most basic data transfer requirements.
You can plug and unplug USB2.0 sync cable directly without powering off or restarting the equipment. Equipment system will automatically identify and match the connected device by high speed USB 2.0 cord. Meanwhile, Hot-swappable plug design of USB2.0 port effectively prevents device damage caused by reversed insertion, making it ideal for frequent daily use scenarios.
USB 2.0 power cables adopt a classic 4-pin structure, including VCC (power positive), GND (power negative), D+ and D- (data pins) with clear functional divisions. 5V/500mA standard power supply does not easily damage device batteries and main-board. Mainly used to supply power and charge low-power peripherals, such as keyboards, mice, Bluetooth headsets and small card readers.
USB 2.0 protocol is fully compatible with all USB 1.0 and USB 1.1 devices. Meanwhile, it can work seamlessly with new-generation interface devices such as USB 3.0, USB 3.1 and USB-C. Supports both old and new devices, no need to distinguish device versions, delivering an extremely wide range of compatibility.
USB2.0 charging and data cable adopt mature manufacturing processes with low production costs. Featuring stable wire construction and wear-resistant connectors, they have a low failure rate in daily use. Compared with high-speed USB3.0 cables or USB3.1 Cables, USB2.0 cable is more suitable for long-term and frequent daily applications.

Advantages of USB 2.0 Cables
Low Cost: Mature manufacturing processes and lower material requirements
Longer Transmission Distance: Standard USB 2.0 cable supports up to 5 meters without a repeater; USB 2.0 active extension cables can easily reach 10 m, 20 m, or even 50 m.
Low Power Consumption and Supply Demands: Provide 500 mA standard power output, placing minimal load on the host. Sufficient for low-power devices like mice, keyboards, USB flash drives, card readers, and audio equipment, requiring no external power.
Strong Anti-Interference and Low EMI: With data rate of only 480 Mbps, signal spectrum is narrow, easing shielding requirements. In industrial environments or long distance situation, USB 2.0 cables suffer less electromagnetic interference and more gradual signal attenuation, ensuring more reliable transmission.
Mature, Stable, and Well-Established Ecosystem: Over 20 years of technological refinement , related USB2.0 chip solutions, cable standards, and testing procedures extremely mature. All mainstream host controllers and peripheral chips fully support USB 2.0, resulting in low failure rates and easy debugging.
Disadvantages of USB 2.0 Cables
Slow Data Transfer (Primary Bottleneck): Theoretical USB2.0 bandwidth is 480 Mbps (~60 MB/s), real-world speeds typically 30–40 MB/s. Much slower than USB3.0 and USB3.1 speed.
Weak Power Delivery: USB2.0 ports supply is only 5V / 500mA (2.5W), not suitable for high-draw peripherals like portable hard drives, external optical drives, LED lights, USB fans, or desktop vacuums.
No Video Output Support: Bandwidth and protocol design do not support DisplayPort Alt Mode, HDMI, or other video signals. Need chipset to change it with high cost.
Half-Duplex Communication: USB 2.0 Data can only flow in one direction at a time (half-duplex), simultaneous send/receive is not supported by USB2.0 data cable.
Higher CPU Overhead: USB 2.0 relies on the host CPU for packet framing and error checking (interrupt transfers), consuming CPU resources during heavy traffic.
Insufficient Bandwidth for Emerging Peripherals: High speed USB2.0 cable do not support high-resolution video devices, such as: 4K/8K cameras, VR/AR headsets, Multi‑channel audio interfaces.
Applications of USB 2.0 Cables
Despite the rise of USB 3.0 cable and USB-C cable, USB 2.0 cables remain essential for a wide range of applications.
Office & Work Environments
USB 2.0 to USB 2.0 cable can be used to connect computers to distant printers, scanners, fax machines, and all-in-one devices for remote printing, scanning, and faxing.
Home & Personal Use
2.0 USB cable can be used to link PCs to speakers, projectors, and external sound cards for multimedia playback and home entertainment.Attach game controllers, steering wheels, and VR trackers.
Industrial & Professional Systems
Used in factory automation to connect PLCs, barcode scanners, and diagnostic tools over longer distances. Deploy for surveillance cameras and data loggers – active USB 2.0 extension cables (up to 50 m) ensure reliable signal integrity.
Retail & Education
USB2.0 printer cable can be used to connect POS terminals, receipt printers, and customer displays in retail checkouts. Link projectors or interactive whiteboards to teachers’ computers in classrooms.
Long Distance Extension (Active Cables)
Extension cable USB 2.0 is Perfect for conference room cabling, remote server management, and outdoor digital signage, where USB 3.0 would fail due to shorter reach and higher cost.
Legacy Device Support
Many older peripherals (e.g., industrial controllers, vintage printers, medical equipment) have only USB 2.0 ports. Cable USB 2.0 keeps them operational without costly upgrades.
How to choose suitable USB 2.0 Cable
USB2.0 Type-A connector: Standard rectangular, connects to computers and chargers.
USB2.0 Type-B connector: Square – common on printers, scanners, and older audio interfaces.
USB2.0Mini-B connector: Older digital cameras and portable drives.
USB2.0 Micro-B connector: Legacy Android phones, Raspberry Pi, and many development boards.
AWG (American Wire Gauge) determines conductor thickness. Lower numbers mean thicker wires and lower electrical resistance. USB2.0 data cables requires a twisted 28AWG Pairs wire as data lines, two twisted wires as power supplier wire. Common power wire size is 28AWG, if you need high power, 24AWG or 20AWG wire is ok for you.
Essential for Signal Stability
Shielding protects against electromagnetic interference(EMI)and radio-frequency interference (RFI). In noisy environments (factories, server rooms) or for runs longer than 1.5 metres, shielding becomes critical.
Breaking the 5.0 Meter Barrier
USB2.0 Passive cables (≤ 5 m) : No internal electronics. Suitable for short connections.
USB2.0 Active cables (> 5 m) : Built-in signal repeaters chips regenerate the signal. Support 25 meters, 50 meters, or even longer distance.
